PRESET HUB ASSEMBLY - ConMet

1 PRESET HUB ASSEMBLYI nstallation Procedures1. Clean the spindle to remove any lubricant, corrosion prevention coating, foreign material, or surface rust that may be Lubricate the bearing journals on the spindle, or the inside diameter of the bearing cones with Grade 2 grease or the lubricant that will be used in the wheel Lubricate the inside diameter of the seal with the same lubricant that will be used in the wheel Leave the shipping cap in place on the hub ASSEMBLY or hold the bearing spacer and the outer bearing cone in place while you place the hub ASSEMBLY onto the spindle. Use a smooth, firm motion and position the hub all of the way onto the spindle. Use care to maintain alignment between the spindle, the bearing cones, and the bearing spacer to prevent damage to the seal or the ABS tone Torque the spindle nut to the following torque values: 6. Install the hub cap or drive axle with a new gasket. Torque the hub cap bolts in a star pattern to 12 to 18 ft-lbs.

2 Torque the drive axle bolts or nuts per the drive axle manufacturer s recommendation. One Piece Spindle Nuts: Torque a one piece spindle nut to 300 ft-lbs while rotating the hub. DO NOT BACK OFF THE SPINDLE NUT. Engage any locking device that is a part of the spindle nut system. If the locking device cannot be engaged, advance the spindle nut until the lock can be Jam Nut Systems: Torque the inner spindle nut to 300 ft-lbs while rotating the hub. Advance the inner nut as necessary to engage the locking ring. DO NOT BACK OFF THE SPINDLE NUT. Install the outer spindle nut and torque it to 200 ft-lbs. Be sure to engage any locking : Failure to fill the hub with the correct amount of lubricant can cause premature failure of the PRESET hub ASSEMBLY , which, if not avoided, could result in death or serious : Use the proper hubcap for the type of lubricant intended to be : Always tighten the top nut first to fully seat the brake drum on the drum pilot and against the hub face.
